Abstract

<p>Gas-liquid interfacial flows, such as liquid film flows (also known as wetting flows on plates), are encountered in many industrial processes including absorption, distillation and so on. The present study focuses on detailed descriptions of the transition phenomena between the film flow and the rivulet flow, as well as how such phenomena are affected by surface texture treatments on plates. This study uses a numerical simulation of Computational Fluid Dynamics (CFD) with the Volume of Fluid (VOF) model as well as an experimental measurement technique. Through the comparison of two geometry cases (smooth surface and wavy surface) which are the models simplified from typical structured packings, the numerical and experimental results show that surface texture treatments can help to prevent the liquid channeling and can increase the wetted area. The main reason for increasing the wetted area on the wavy surface is that the liquid film break-up is inhibited due to the increasing of liquid film thickness on the plate as well as the spreading of the liquid flow in spanwise direction by the wavy surface geometry.</p>
